github.com/authzed/spicedb: SpiceDB: Improper cache reuse vulnerability in caveat structures
SpiceDB is an open source database system for creating and managing security-critical application permissions. From version 1.15.0 to before version 1.52.0, caveat structures with nested lists can result in improper cache reuse. This issue has been patched in version 1.52.0.
A flaw was found in SpiceDB, an open-source database system for managing application permissions. This vulnerability occurs due to improper cache reuse when processing caveat structures that contain nested lists. This could lead to unexpected behavior or a low impact on confidentiality, potentially resulting in minor information disclosure.

SpiceDB: Caveat structures with nested lists can result in improper cache reuse
### Impact
Users are impacted if:
- They have a caveat structure with a nested list, e.g.:
```zed
caveat shape(x list) {
x == [["a"], "b"]
}
```
- Their system exercises that caveat with either [CheckBulkPermission](https://buf.build/authzed/api/docs/main%3Aauthzed.api.v1#authzed.api.v1.PermissionsService.CheckBulkPermissions) or else [LookupResources](https://buf.build/authzed/api/docs/main%3Aauthzed.api.v1#authzed.api.v1.PermissionsService.LookupResources) running with the `--experimental-lookup-resources-version` flag set to `lr3`, implying they are using the experimental version 3 of `LookupResources`
- An attacker can cause the system to craft a request to SpiceDB where either:
1. It's a `CheckBulk` req
